Abstract : The experience of the road in international migrations consists in knowing how to cross not only the state borders, but also the constabulary roadblocks positioned at intervals all along the route. Within the context of the migration of Tuareg populations from Niger (Bankilaré area) towards Abidjan, the route gave rise to the creation of original and transient socio-spatial structures, such as places, boundaries, borders (imaginary or not), which are all answers to the strangeness of the spaces crossed and to the fear associated to them.
